The term billboard is used to refer to those hanging structures that are normally located on walls or in well-visible spaces in which notices, notifications, dates and different important information are placed so that interested people can access it and be aware of the transmitted data. In a perhaps a little more metaphorical sense, the term is also used to talk about the cinema, theater and other shows that are presented at the moment in each region (for example in a city) even though they are not explicitly communicated through a billboard.
The billboards are well known and common in spaces in which a lot of information is poured and those who pass through the place are invited or requested to find out about different data. Some of the most common settings are schools, universities, workplaces, doctors' offices, supermarkets, banks, etc. All these spaces use the billboard as a quick, easy and accessible method to communicate data to a significant amount of the population, thus avoiding wasting time having to communicate everything to those who need it. The idea of the billboard also supposes in a certain sense that, when the information is placed there, it is the responsibility of the interested parties to keep informed about this exposed data.
Billboards can be very different from each other depending on the space in which they are placed. Thus, a student billboard will not be the same as a bank billboard, not only because of the type of information that is released in each case, but also because of the type of language that will be used, the different ways of drawing attention to those who are will recur, etc. For example, a bank billboard is much more sober and formal than that of a student center, perhaps more messy, colorful and informal.
